Logical metatheorems for accretive and (generalized) monotone set-valued operators [PDF]

open access: yesJournal of Mathematical Logic, 2023
Accretive and monotone operator theory are central branches of nonlinear functional analysis and constitute the abstract study of certain set-valued mappings between function spaces. This paper deals with the computational properties of these accretive and (generalized) monotone set-valued operators.

System of Nonlinear Set-Valued Variational Inclusions Involving a Finite Family of H(·,·)-Accretive Operators in Banach Spaces [PDF]

open access: yesJournal of Applied Mathematics, 2012
We study a new system of nonlinear set-valued variational inclusions involving a finite family of H(·,·)-accretive operators in Banach spaces. By using the resolvent operator technique associated with a finite family of H(·,·)-accretive operators, we ...

Topological Degree for Operators of Class (S)+ with Set-Valued Perturbations and Its New Applications [PDF]

open access: yesFractal and Fractional
We investigate the topological degree for generalized monotone operators of class (S)+ with compact set-valued perturbations. It is assumed that perturbations can be represented as the composition of a continuous single-valued mapping and an upper ...
